124. From that article I put us at 49

with one very easy way to get to 50. First we are at 49 because we had 44, Reid switching gives us 45, Kohl and Webb were replaced by Baldwin and Kaine that's 47, Brown and Snowe were replaced by Warren and King that is 49. Now the easy 50. Appoint Kerry to SOD or SOS in December and have him replaced by an appointed Senator who favors reform. You now have 50.
